In the case of such "very large networks", it might actually make sense
to re-establish something like "enterprise LIRs".  Allocation would
then, of course, only be to enterprise-internal structures, and some
special policy might apply to "do they get an allocation?", but I would
not clearly say "no" --> we should have a special-case clause in the
policy...

On the other hand, I do not want a small "we have 200 employees, 3
locations, and we're sooooooooo important" company to use address 
space that leads to a globally visible route.


Responding to your e-mail about the way "ISPs" and "enterprises" do
address management: the very fact that enterprises get a large chunk 
of "PI" address space (one more route in the global tables already)
and then *fragment that* to generate *even more* routes in the global
tables is something that makes me think whether it might not be more
useful to use multiple PA blocks, from the various regional ISPs 
that you're multihomed to.

Like "Cisco EU is connected to UUnet 702 and uses a /18 from their PA 
space.  Cisco US is connected to Genuity and uses a /17 from *their*
PA space, etc., and all the PA blocks are only announced to all the 
direct upstreams (and internally, of course), but not to 'the world'".  

I'm not sure how feasible this would be for any specific network, but the 
whole thing of artificially generating more and more and more routes 
bothers me.
